lb/in force exerted on front "torque rod"

[meatz]

I'm looking into the idea of fabbing my own front engine mount/torque rod. I'm thinking either some sort of pneumatic or spring resistance type device. Although not the typical beginner question, my posts are limited to here for now. Question is this, How much force (hereabouts) is applied to the front torque rod under acceleration events? (and by how much will that increase from NA to FI?) Approximations or better yet, a link to the how and the why of it would be great.

I cant give you any numbers but in the past i swore i saw a guy who was running a turbo fab up a front mount basically consisting of something that looked like a spring/dampener from a rear section of a mountain bike. Its been forever since ive seen the guy post but maybe you can head over to the forced induction area and browse around.

I think his name was Chessboxer or something like that but he was from Lexington.

*edit

HEY it's your lucky day i found his DIY.

That design is backwards because the front of the motor lifts. You would be better off making a solid front mount or better yet focusing on the rear mount.

A "shock" type device mounted to the firewall could be useful for this... though regular engine movement would be necessary to allow, and the mounting point would likely need to be reinforced.

Unfortunately, I don't think anyone has measured the actual force applied to the front mount... or has the means to.

Although I do need to replace the rear one too, my focus is on the front right now because with my 'soon to be' setup, the OEM one won't go back where it came from. And I'm looking to restrict the motor's movement, but in a fashion so as not to sacrifice too much ride quality. I am of the opinion that no matter what, a car should stick to the road, like white on rice. But to do so and maintain a comfortable ride, that's just high quality, grade A craftsmanship/forethought.

Thanks Leung. That link was very helpful.

Hey no problem man, hope you figure out something.

Most turbo guys guys reinforce the other 3 mounts, and run without the front mount. Since it's not load-bearing, it's not absolutely necessary, as long as the other 3 are up to the task (the rear especially, which is why sordz mentioned it)
